Did you know Etsy offers several tax resources for Sellers?
For a basic tax overview, check out Tax 101.
For Sellers making over $20,000.00 in gross sales with over 200 sales, more information on the 1099-K Form (new last year) is available in the article Talking Taxes: 1099-K Forms for U.S. Sellers.
And for those crazy few of us who actually like the mental challenge of crunching the numbers, there are actually tax-related teams on Etsy. I recently joined the U.S. Tax, Bookkeeping and Business License Topics Team.
The tax season is still young. Don't panic. Breathe.
